AN: This one's brief because they're all annoying. I don't own any of this; I am but a puppet master. More to come.
"Curse you, Kim Possible!" Drakken cries, frantically analyzing his command center for any way to prevent the increasingly inevitable. His hands fly over the controls, editing every dial, knob, and button within his reach. His face falls as he realizes his compromised position, and turns to run after Ron, who had already fled the foreseen danger of staying near the console.
"You think you're all that," he huffs, taking a step toward Kim and Shego fighting on the ground below him. As the exploding console launches him up out of the hole in the ceiling created by the falling support pillars, he screams, barely audible, "but yooou're nooooooooooooot!" Kim pauses when she hears her name, awe-struck at his trailing exclamation. Her opponent, not having observed the extent of the damage, seizes this opportunity to land a roundhouse kick to the side of the teenager's chest, hurtling her toward the explosion. As she hits one of the few pillars still standing, the sickening crack of breaking bones can be heard.
Shego stands amazed; both at herself, for being so rough, and at Kim, for not perceiving and blocking her attack. Her clenched and raised fists are forgotten, and they fall slowly to her sides as she watches. She is unable to propel herself into action as the crumpled body of her rival is enshrouded by smoke, flame, and debris that falls from the ceiling and flies from the explosion. The sharp sound of a metal staircase crashing to the ground wakes her from her trance, and she launches blindly forward.
"Kim!" she cries, terror stricken. She coughs as the harsh cloud infiltrates her lungs and stumbles forward, feeling her way. When she finds the hero she shakes her by the shoulder, willing her to wake. Receiving no response whatsoever, she feels for the muted pulse of the girl and lifts her onto her back to carry her to safety. The jostling run out of the building wakes Kim, but the pain in her back and hips screams her into submission and she passes out. Shego feels her relax and whispers, "hold on, Cupcake. We're almost home." They dodge out of the lair as it collapses around them. Shego relaxes for a moment as the cave that leads to her home comes into view, then redoubles her strength and continues running.
